Description
technical field [0001] The invention relates to the technical field of asphalt material preparation, in particular to an integrated preparation device and method for esterified bio-asphalt. Background technique [0002] At present, the demand for asphalt materials in large-scale high-grade highway asphalt pavement construction and maintenance projects continues to increase, and non-renewable petroleum asphalt resources are gradually depleted. Seeking sustainable alternative materials for petroleum asphalt has become an urgent demand in the international road field. Asphalt came into being. Through the research on the conventional performance of bio-asphalt, it is found that bio-asphalt has defects such as poor water stability, low-temperature hardness and brittleness, and is currently difficult to be directly applied to road construction. Therefore, some researchers have carried out esterification and catalytic reactions on bio-asphalt to generate Esterification of bio-asph...
